quick cardio drug spitfire Flashcards
digoxin
inhibits Na/K pump resulting in more calcium available which improves contractility, lots of adverse effects
pimobendan
an ionodilator
sensitizes troponin C to calcium, imporving the strength of contraction, reduces preload and afterload
dobutamine/dopamine
dobutamine: beta 1 agonist, short half life, given CRI, used in hospital
epinephrine
non selective adrenergic agonist, increases HR and positive inotrope, is also a bronchodilator due to beta 2 effects, used for emergencies only
propanolol
non selective beta blocker, neg chronotrope, and a vaso/bronchodilator
atenolol
selective beta 1 blocker, use over proanolol is concern for lungs
atropine
anticholinergic, increases cAMP, increases HR and cardiac output
lidocaine
fast sodium channel blocker, decreasing conduction velocity, treat ventricular tachyarrhtymias
quinidine
a fast sodium channel blocker, decreasing conduction velocity, treats atrial arrthymias and increases effective refractory period
procainamide
fast sodium channel blocker, decreasing conduction velocity, for ventricular arrhytmias
sotalol
potassium channel blocker, slows repolarization, also a beta blocker, for ventricular arrthymias
Amlodipine
calciu,m channel blocker, mostly works on vasculature, causes vasodilation and decreases afterload, first choice for CKD in cats
diltiazem
calcium channel blocker in nodal tissue, vasodilator, neg dromotrope/notrope/chronotrope
enalapril
ACE inhibitor: vasodilation and decrease afterload, diuretic
benazapril
ACE inhibitor: vasodilation and decrease afterload, diuretic
